Abstract: | We discuss the various mechanisms potentially at work in hadroproduction of heavy quarkonia in the light of computations of
higher-order QCD corrections both in the colour-singlet (CS) and colour-octet (CO) channels and the inclusion of the contribution
arising from the s-channel cut in the CS channel. We also discuss new observables meant to better discriminate between these different mechanisms. |
